Polymeric one‐dimensional (1D) triazole‐based Fe II spin crossover nanoparticles have been entrapped in pluronic P123 matrix, forming nanorods in which the interaction between host (P123) and guest (Fe II complex) promoted high reproducibility of the spin crossover process, significant shifts of the transition temperatures ( T ↑=370 K, T ↓=338 K for the P123 entrapped material vs the literature values of T ↑=358 K, T ↓=341 K for the neat/polymer free system) and larger magnetic hysteresis width.
